Took the valve from the rear and rewired them,

Front still won't air up or do anything,
Rear work just fine..

when you hit the switches do you hear the valves clicking at least? or nothing at all.

re-tefloning the valves and fittings wont help a non working valve btw lol only leaks. hehe

you can check to see if youre getting power to the front valves with a multimeter. If there is no power when you hit the switch then you can limit your search to the switch box or something

Yeah I think I can hear the valves..

No the reason why I reteflon the fitings is cause Im having a air leak.. I took a soapy water and sprayed and saw some leaks so I took it apart and reteflon eveytthing put them back together and now I'm having problem

He reason why I switch the valves is to see if I have a bad valve..

guaranteed wiring problem.
if u press it and valve doesnt actuate, its wiring problem.
if hose is clogged, the valve would still actuate when press the UP

Ok no wiring problem..all the valves are working..
Checked the hose and there's no air comin out so it's not supplying air to the front...I bought a regular air hose from home depot and now front air up but ders a huge leak on the valve..
Because I use a regular air hose?
